Math Problem Statement

Find the inverse of the relation {(1, 0), (3, -8), (4, -3), (7, -5), (9, -1)}

Solution

To find the inverse of a relation, we swap each ordered pair's xx-coordinate and yy-coordinate. The inverse of the relation R={(1,0),(3,8),(4,3),(7,5),(9,1)}R = \{(1, 0), (3, -8), (4, -3), (7, -5), (9, -1)\} is obtained by flipping the pairs.

Here’s the process:

  • The inverse of (1,0)(1, 0) becomes (0,1)(0, 1)
  • The inverse of (3,8)(3, -8) becomes (8,3)(-8, 3)
  • The inverse of (4,3)(4, -3) becomes (3,4)(-3, 4)
  • The inverse of (7,5)(7, -5) becomes (5,7)(-5, 7)
  • The inverse of (9,1)(9, -1) becomes (1,9)(-1, 9)

Thus, the inverse of the given relation is: R1={(0,1),(8,3),(3,4),(5,7),(1,9)}R^{-1} = \{(0, 1), (-8, 3), (-3, 4), (-5, 7), (-1, 9)\}

Here are 5 related questions to extend your understanding:

  1. What does it mean for a relation to have an inverse?
  2. How do you determine if a relation is a function?
  3. Is the inverse of a function always a function? Why or why not?
  4. Can you graph both the relation and its inverse to visualize the process?
  5. How do you determine if an inverse relation is also a function?

Tip: For a function to have an inverse function, it must be both one-to-one (injective) and onto (surjective).
